HY
Key facts
Chemically resistant HDPE 1.5–2.0 mm for ponds and tanks, with rounded base/wall transitions, pre-installed pipe sleeves, and full weld plus flood testing.
Configuration must be confirmed by project design documentsMaterial Configuration by Layer
| Layer | Recommended material | Function / rationale |
|---|---|---|
| Primary liner | HDPE 1.5–2.0 mm (chemical-resistant grade) | Containment |
| Base/wall transitions | Rounded fillets | Avoid stress concentration |
| Penetrations | Sleeves/flanges + patch + sealant | Seal inlets/outlets |
| Testing | Weld air/vacuum + flood test | Verification |
| Note: configurations are common practice; the final system and specifications must follow the project design documents and governing codes. | ||
